Draw faster circles with Python turtle

Question

I have an exercise wherein I have to draw a lot of circles with Python turtle. I have set speed(0) and I am using:

from turtle import*
speed(0)
i=0
while i < 360:
    forward(1)
    left(1)
    i+=1

to draw circles. It takes so long. Is there any faster way?

Answer 1

Have you tried turtle.delay() or turtle.tracer() ? See documentation here and here . These set options for screen refreshing which is responsible for most of the delays.

Answer 2

You could draw fewer segments, so rather than 360 you go for 120:

while i < 360:
    forward(3)
    left(3)
    i+=3

That will make your circle less smooth, but three times faster to draw.

Answer 3

circle() 方法可能不会更快，但可能更容易管理： turtle.circle()

Answer 4

Turtle has a function for drawing circles and the speed of that is much faster than going in a circle one step at a time.

 import turtle
 tina=turtle.Turtle()
 
 tina.speed(0)
 tina.circle(70)

It will look like this

Answer 5

Use Multithread to draw two semi circles simultaneously. Initially the turtle will be at (0,0) so just clone the turtle and make them both face in opposite direction by 180° then draw semicircles. The code is below:

from threading import Thread
import turtle
t = turtle.Turtle()
t.speed(0)
def semi1(r):
   r.circle(50,180)
def semi2(t):
   t.circle(50,180)

r = t.clone()
r.rt(180)

a = Thread(target=semi1).start()
b = Thread(target=semi2).start()

This may draw the circle fast.
